Hello all! my TT has been running like a bag of nails for a while now I have checked everything I can but all fine, ran ECU test and Im sure a different code came up first? like 34 or 43?? but then code 55 and stayed code 55 after that! the idle is lumpy going up and down from 400-900rpm sometimes cuts out, I can smell fuel at times but no fuel leaks. I cleaned every connector I could see with most of them with blue corrosion on but no change so I took connector off TPS which was dirty so cleaned it up and now im sure the zed runs worse, even more lumpy? So could this be a dodgy TPS?? Can it be adjusted?? I dont want to pay for a consult if I can help it but I have checked everything. If anyone can help that would be great!!

you should clean the throttle bodies...carb cleaner and some rag....then worry about adjusting things

 

smell of fuel....it could be the regulator on top of the plenum the hose clamps need nipping up often you cant see it leak as it runs down the pipe and evaporates off

pop up and we wil look at it !

The throttle bodies were cleaned end of last year when cambelt was done but I done them again couple days ago just incase! Not sure what the regulator looks like but there was a small leak last year right at the back of plenum which I have checked again but no leaks? will go round and tighten all fuel pipes just incase but cant see there will be any change??

pop up and we wil look at it !

 

Hello Paul! Probably looks like the best idea!! cant do today as its my daughters 1st birthday or tomorrow as its her party! I could probably do sometime next week?

can we have a picture of the fuel pressure regulator please

That would be handy!

i THINK its the little filter lookin type thingy that sits in the end of the fuel line at the back of the plenum cos mine buzzes after the throttle got stuck on lol.
